The new generation Centrifugal Air Blowers are used in those applications where the need of air for suction, blowing, combination, dust collection and scrubbers etc. They are mainly designed with impellers of backward and forward curved blades, aluminum, mild steel, FRP, & Heat resistant – materials. These blowers are equipped with highly advance motor and designed with strong metallic body to make sure its robustness and durability. Due to its excellent functionality, high efficiency, less maintenance and long shelf life, these Ventilation Centrifugal Air Blowers are widely demanded in the market.
Axis centrifugal air blowers had three variants which are
1.Direct Drive (DD)
2. Belt Drive (BD)
3. Coupling Drive (CD)
Direct Drive : It is mounted on the motor shaft. Thus, the speed of the impeller will be as same of motor used in ambient air handling requirements.
Belt Drive: Impeller will be mounted on the rearing shaft and it will be driven by the motor shaft through pulleys & belt. Impeller speed can be designed based on the customer requirements. But it has limitations like torque, pressure, volume and load current .
Coupling Drive: Impeller will be directly coupled with motor. This model is widely used in places where the requirements of motor load are huge. In this case, impeller speed will be as motor sped. But motor torque will be minimized on the impellers due to
Axis centrifugal air blowers are designed for Pressure
